20 Claims.

This invention relates to lasting machines, and is herein illustrated as applied to a power-operated toe-lasting machine which, except as hereinafter noted, is constructed generally as disclosed in United States Letters Patent No. 2,160, 846, granted on June 6, 1939, on an application of F. C. Eastmans and A. F. Pyms. It is to be understood, however, that the invention is not thus limited in its applicability.

The machine shown in the above-mentioned Letters Patent is provided with wipers which are moved by a wiper carrier heightwise of the last to wipe the toe-end portion of the upper in that direction and are then operated to wipe the marginal portion of the upper inwardly over an insole on the last, and also with grippers which apply a pull to the upper at the end and the sides of the toe and thereafter control it during the greater portion of the wiping operations of the wipers. It has been proposed heretofore to substitute for such grippers a device having the function of what is commonly known as a retarder, the device being arranged to clamp the marginal portion of the upper outspread on the wipers about the end and along the sides of the toe and to cooperate with them in applying a pull to the upper and having the further function of maintaining the marginal portion of the upper smoothly outspread to assist in preventing the formation of any objectionable wrinkles in the course of the toe-lasting operation. Such a device or retarder is shown, for example, in United States Letters Patent No. 2,380,407, granted on July 31, 1945, on an application of mine. The present invention, in one aspect, provides novel toe-lasting means including a retarder controlling the upper generally as above described and grippers which grip the marginal portion of the upper at the sides only of the toe and serve as supplemental means for pulling and controlling the upper in those locations, thus affording further insurance against any looseness or wrinkling of the upper at the sides of the toe near the portions thereof beyond the toe which in accordance with the usual practice have already been lasted prior to the toe-lasting operation. In the construction shown the grippers engage the margin of portions of the upper which are also controlled by the retarder, and both the grippers and the retarder permit the upper to slip relatively thereto in response to its resistance to the force of the pull applied as the upper is wiped heightwise of the last by the wipers. Preferably, moreover, the retarder andthe grippers continue their control of the upper until the wipers begin to wipe its marginal portion inwardly over the insole. For operating the grippers to pull the upper the construction shown provides mechanism which is operated by the movement of the wiper carrier heightwise of the last, comprising an operating. device connected to both grippers and extending into the pathof movement of the wiper carrier. Novel means also are provided for closingthe grippers on the upper simultaneously with the movement of the retarder into position to clamp the upper on the wipers, the construction shown comprising a cam-operated rockshaft having an arm thereon for thus moving the retarder and provided also with other arms acting on members which close the grippers. I

The above and other features of the invention, including various novel details of construction and combinations of parts, will now be more particularly described with reference to the accompanying drawings and thereafter pointed out in the claims.

In view of the disclosure in the above-men.-

the parts tioned Letters Patent No. 2,160,846, as much of the machine herein shown as is common to that prior disclosure will be herein described only in so far as is necessary for an understanding of the present invention. The position of a welt shoe and its last presented to the machine bottom upward by the operator is determined by a member 2 arranged to engage the bottom face of the toe end of the insole adjacent to its welt-attaching lip a and also to engage the inner face of the lip about the end and along the sides of the toe. The member 2 is detachably supported on the lower end of a post 4 adjustable vertically in bearings in the frame by a hand wheel 6. Immediately after the starting of the cycle of power operations of the machine the shoe is clamped against the member 2 by a toe rest 8 which is moved upwardly to clamping position. For lasting the toe end of the shoe the machine is provided with a pair of Wipers I which are advanced lengthwise of the last and are closed inwardly widthwise of the last to embrace the upper closely about the toe end of the last and are moved upwardly to wipe the wiper heightwise of the last, after which they are further advanced and closed to wipe the marginal portion of the upper inwardly over the feather and against the lip of the insole. The wipers are supported by a wiper carrier l2 mounted for swinging movement to carry them heightwise of the last about a connection (not shown) with a lever M (Fig. 1) by which the carrier and the wipers are advanced lengthwise of the last. Closing movements relatively to the wiper carrier are imparted to the wipers by mechanism including a bell-crank lever 16 on the carrier. For a better understanding of the construction of the wiper-operating means Letters Patent No. 2,160,846 may be consulted.

Instead of the grippers shown in Letters Patent No. 2,160,846 for pulling the upper, the machine herein shown has other means cooperating with the wipers to last the toe end of the shoe, including a device l8, herein termed a retarder, which clamps the marginal portion of the upper outspread on the wipers. This retarder, which is similar in construction to that shown in Letters Patent No. 2,380,407, comprises a pair of upperclamping members 20 each arranged to engage the upper along one side and part way around the end of the toe, and a central upper-clamping member 22 arranged to bridge any space between the two members 20 at the end of the toe. The two members 20 are mounted on a rod 24 for adjustment toward or from each other in directions widthwise of the shoe, this rod being secured in the lower end of an upwardly extending bar 26 controlled as hereinafter described. The central member 22 is provided at the opposite sides of the bar 26 with a pair of ears 28 (Fig. 2) whereby it also is mounted on the rod 24, and it is arranged to overlap and to engage fiat faces on the two members 20 so that all three members are held in fixed relation to one another for movement as a unit about the rod 24. For adjusting the two members 20 toward or from each other there are provided two latch members 30 slidingly mounted on a rod 32 secured in the bar 26, these latch members being arranged to extend into grooves 34 (Fig. 2) formed in portions of the members 20 which are located above the rod 24. Threaded on the opposite end portions of the rod 32 are nuts 36 each provided with a flange 38 arranged to lie in a groove formed in the hub of the latch member 30 associated therewith. The

latch members are normally held in the grooves 34 by springs 40 connected to a pin 42 extending through the bar 26, but may be swung against the resistance of these springs to release the members 20 and permit them to be removed from the rod 24 if desired. In the construction herein shown, as distinguished from that disclosed in Letters Patent No. 2,380,407, portions of the ears 28 which extend upwardly above the rod 24 are further connected by a pin 45 to a link 46 which is forked to eXtend upwardly at opposite sides of the bar 26 and is provided at the opposite sides of the bar with slots 48 through which the rod 32 extends. These slots permit limited tipping movement of the retarder I8 about the rod 24, so that the retarder is free to adjust itself to the plane of the wipers when it first clamps the margin of the upper on the wipers and maintains a parallel relation to that plane as long as it continues thus to clamp the upper.

In the construction herein shown the bar 26 which supports the retarder is controlled by an arm 50 fast on a rockshaft 52 arranged to extend laterally of the shoe and mounted in bearings in the frame. The arm 50 is forked (Fig. 2) and carries a pin 54 extending through slots 56 formed in portions of the bar 26 which are spaced from each other by a slot 58 (Fig. 2) extending lengthwise of the bar. Mounted on the pin 54 in the slot 58 is a block 60 in which is threaded the lower end of a rod 62 extending upwardly within the bar 26 and surrounded by a spring 64 bearing at its lower end on a shoulder on the bar. Threaded on. the upper end of the rod is a nut 66 which, in accordance with its adjustment, holds the spring under more or less initial compression, the pin 54 being positioned initially at the upper ends of the slots 56 (Fig. 5). A lock nut 68 holds the nut 66 in adjusted position. It will thus be seen that the bar 26 and the retarder I8 are supported initially at a height determined by the position of the arm 59, as illustrated in Fig. 5. At a predetermined time in the operation of the machine, prior to the effective upwiping action of the wipers 0n the upper, the retarder is moved downwardly by the arm 59 to clamp the marginal portion of the toe end of the upper outspread on the wipers, as illustrated in Fig. 8, in response to turning movement of the rockshaft 52. For thus ,turning the rockshaft there is fast thereon an arm 10 (Figs. 1 and 3) connected by a link 12 to one arm of a lever 14 mounted to turn about a shaft 16, the other arm of the lever having thereon a roll 18 engaged by the periphery of a cam fast on the operating Cam shaft 82 of the machine. The cam 80 includes a cam plate 84 adjustable about the axis of the shaft 82 to determine variably the time in the operation of the machine when the rockshaft 52 is operated to move the retarder into upper-clamping position, the cam plate being held in adjusted position by screws 86 extending through slots therein. A spring 88 connected to the lever 74 holds the roll 18 at all times in engagement with the cam and serves to return the retarder to its initial position when permitted by a drop 00 on the cam.

After the retarder has been moved downwardly into upper-clamping position as above described, the arm 50 is held stationary by the cam 80 during the upwiping movement of the wipers. Accordingly the retarder and the bar 26 are lifted by the wipers against the resistance of the spring 64, the nut 66 entering the opening in the bar in which the spring is mounted, as illustrated in Fig. 9. Further to control the bar 26 with respect to swinging movement about the pin 54, and thus to determine the position of the retarder length wise of the shoe, there is provided a cam block 92 having therein a cam slot 94 in which lies a roll 96 mounted on one side of the bar 26. This cam block is pivotally mounted at its upper end on a pin 98 supported by two ears I00 projecting forwardly from a plate I02 fast on the frame. Pivotally connected at I94 to the lower end of the cam block is a pin I86 extending 'rearwardly through an opening in an ear extending ,downwar'dly from the plate I92 and having threaded thereon a thumb nut I08 engaging the rear face of this car. Between the ear and the lower end of the cam block is a compression spring I I0. The thumb nut and the spring thus cooperate in adjusting the cam block 92 about the pin 98 to determine variably the initial position of the retarder lengthwise of the shoe. The lower end portion of the cam slot 84, in which the roll 96 lies during the upwiping movement of the wipers, is inclined in such manner as to swing the bar 26 in a counterclockwise direction with reference to Fig. 8 as the bar is lifted by the wipers, thus causing the retarder to move in an outward direction lengthwise of the shoe over the margin of the upper with a smoothing and tightening action thereon in the course of the upwiping operation.

In addition to the retarder, the machine herein shown is provided with two grippers I I2 arranged to grip the margin of the upper respectively at the opposite sides of the toe to assist in the t0elasting operation. Preferably, as shown in Fig. 6, these grippers act on portions of the upper which are also controlled by the end portions of the retarder. Each gripper includes a jaw II4 ar ranged to engage the inner face of the upper and a jaw II6 supported on a holder II8 which is pivotally mounted on a pin I secured in an upwardly extending shank portion I22 of the jaw II4. By swinging movement about the pin I20, therefore, the holder II8 carries the jaw II6 toward and from the jaw II4. A thin plate-like portion I24 of the jaw II6 extends into a slot in the holder I I8 and is itself provided with a curved slot I26 through which extend two pins I28 in the holder. The jaw H6 is therefore permitted by the slot I26 and the pins I28 to adjust itself to the upper when it grips the upper against the jaw H4. The shank portion I22 of the jaw H4 is provided with a stem I30 (Fig. 4) extending up" Wardly into a bore formed in the lower end of a jaw carrier I32, the stem having therein an annular recess I34 to receive the end. of a setscrew I36 (Fig. 3) in the jaw carrier. By this setscrew the two jaws are secured on the jaw carrier with provision for adjustment there-of about the axis of the stem I30, the jaw carrier being controlled as hereinafter described.

For closing each gripper 0n the upper there is pivotally connected to the holder II8 which carries the jaw II6 the lower end of a rod I38 extending upward loosely through an opening formed in a block I40 which has thereon a stem I42 mounted to turn in an upwardly and downwardly extending bar I44. This bar is pivotally mounted at its upper end (Fig. 5) on the front end of a rearwardly extending arm I46 pivotally mounted on a pin I48 011 the plate I82. At its lower end the bar I44 is pivotally connected to the front end of an arm I50 fast on the rockshaft 52. Surrounding the rod I38 between a washer I52 bearing on the block I48 and another washer I54 seated on a shoulder on the rod is a compressioh spring I56. On the upper end of the rod are threaded a pair of nuts I58 one of which engages a washer I60 bearing on the upper face of the block I40, It will thus be seen that when the rockshaft 52 is turned to move the retarder I8 downwardly into position to clamp the upper on the wipers, as hereinbefore described, the two arms I50 on the rockshaft impart downward movements to the bars I44, thus causing the blocks I40 to act through the springs I56 and the rods I38 to swing the gripper jaws I I6 into positions to grip the upper against the jaws II4, the springs being compressed more or less to maintain the grip an the upper.

Each gripper jaw carrier I32 is guided for upward and downward movements by a rod I62 (Figs. 3 and 4) extending downwardly through a bearing formed in a forwardly extending upper end portion I64 of the carrier into a bearing in the lower portion of the carrier. The two rods I62 are pivotally supported at their upper ends on studs I66 mounted in a crossbar I68, this crossbar being provided at its opposite ends with forwardly and upwardly curved portions I10 mounted on pins I12 supported by holders I14. Each holder I14 is provided with a stem I16 extending upwardly through a sleeve I18 which is threaded in the frame, the stem having on its upper end a nut I engaging the upper end of the sleeve. The two sleeves I18 may be turned by means of knurled heads I82 formed thereon, and it will be evident 'that in this manner the crossbar I58 may be adjusted upwardly or downwardly. Also mounted on each guide rod I62 to move lengthwise thereof is an L-shaped member I84 normally seated on the lower end portion of the carrier I32 and having fast thereon a sleeve I86 extending upwardly along the rod to assist in preventingfany cramping of the member I84 on the rod. The member I84 carries a pin I88 extending through a slot I90 in the rod I62 to limit downward movementof the member. Between the lower portion of the L-shaped member I84 and the forwardly extending upper portion I84 of the carrier I32 is a compression spring I92. It will thus be seen that by upward movement of the member I84 along the rod I62 upward movement is imparted yieldingly through the spring I92 to the gripper jaw carrier I32 and the gripper jaws to cause the gripper to pull the upper. For thus operating the two members I84 there is provided a crossbar I94 provided with slots I98 into which extend pins I98 carried by the members I84. This crossbar has formed thereon a central boss 200 guided for upward and downward movements on the previously mentioned post 4, the boss having a sleeve 202 extending upwardly therefrom to assist in preventing any cramping of the crossbar on the post. Between the boss 200 and a boss 204 on the frame a compression spring 206 which tends to move the crossbar downwardly, its downward movemerit being limited by the two pins I88 and the slots I90. The crossbar I94 is provided at its opposite ends with downwardly extending arms 208 to which are secured reenforcing pieces 2I0 (Fig. 4), and fastened to these arms are downwardly extending bars 2 I2 provided at their lower ends with rolls 2I4. These rolls are arranged to be engaged by hardened blocks 2I6 (Fig. 3) secured (in the wiper carrier I2. When upward movement is imparted to the wiper carrier, therefore, to cause the wipers to wipe the upper heightwise of the last the crossbar I94 is moved upwardly bythe carrier alon'g'the post 4 to impart upper-pulling movements yieldingly heightwise of the last to the grippers I I2. It will be evident that in this operation the gripper-closing rods I38 also are moved upwardly, further compressing the springs I56 and increasing somewhat the pressure with which the upper is gripped by the gripper jaws. These jaws are provided with smooth upper-engaging faces to permit the upper to slip relatively to the jaws in response to its resistanceto the force of the pull applied thereto. The grippers may be adjusted initially heightwise of the last by turning the sleeves I18, and by this means the crossbar I94 is correspondingly adjusted through its connections with the L- shaped members I84, thus varying the time in the upward movement of the wiper carrier I2 when the upper-pulling movements of the grippers begin.

To determine variably the positions of the grippers widthwise of the last there is associated with each gripper a rod 2I8 (Figs. 3 and 4) having an enlarged head 22D pivotally mounted on a stud 222 threaded in the gripper jaw carrier I32. This rod extends outwardly through an opening formed in an arm 224 provided with a pin 226 mounted to turn in the corresponding bar 2I2. Between the head 220 and the arm 224 is a compression spring 228, and threaded on the rod 2I8 at the outer side of the arm 224 is a thumb nut 238 cooperating with the spring to adjust the gripper widthwise of the last about the stud I66.

The manner of operation of the machine, in so far as it is of interest with reference to the present invention, will now be briefly summarized. The operator presents the shoe to the machine in the position determined by the insole-engaging member 2 with the margin of the toe-end portion of the upper materials outspread from the edge of the insole and with portions thereof at the sides of the toe extending upwardly between the jaws of the open grippers I I2. He then starts the machine, whereupon the toe rest 8 is moved upwardly to clamp the shoe against the member 2 (Fig. 5). Early in the cycle of operations the wipers II] are advanced and closed and are swung upwardly to bring their edges into positions to begin effectively to wipe the upper heightwise of the last, and in the course of these movements of the wipers the rockshaft 52 is turned by the cam 80 to move the retarder I8 downwardly into position to clamp the marginal portion of the upper outspread on the wipers about the end and along the sides of the toe, as shown in Figs. 6, '7 and 8. As the retarder is thus moved downwardly it is guided into proper position relatively to the last and the wipers by the action of the cam slot 94 on the bar 26. When the retarder thus clamps the upper it adjusts itself to the plane of the wipers, which are at that time somewhat inclined lengthwise of the last, by reason of the provision of the slots 48 in the link 46. The retarder may become effective thus to clamp the upper on the wipers substantially at the time when the wipers in their upward swinging movement arrive in positions to begin an effective upwiping action on the upper. As the retarder is thus moved downwardly by the rockshaft 52 the arms I56 on this rockshaft impart downward movements to the two bars I44 which act through the springs I 56 and the rods I38 to swing the outer gripper jaws II6 into positions to grip the portions of the upper which they engage yieldingly against the inner jaws II4. As the wipers are thereafter swung farther upwardly to wipe the upper heightwise of the last they lift the retarder and its supporting bar 26 against the resistance of the spring 64 through which the retarder is pressed yieldingly on the upper, the retarder cooperating with the wipers to apply an upward pull to the upper while the margin of the upper slips more or less inwardly between the retarder and the wipers. At the same time the cam slot 94 acts through the roll 96 on the bar 25 to move the retarder a short distance outwardly over the wipers lengthwise of the shoe with a tightening and smoothing action on the margin of the upper at the end of the toe. In the course of the upwiping action of the wipers the crossbar I94 is lifted by the wiper carrier I2 and acts through the members I84 and the springs 592 to impart upward movements yieldingly to the gripper jaw carriers I32. Accordingly the grippers, which preferably act on portions of the upper also controlled by the retarder at the sides of the toe as shown in Fig. 6, apply a pull to those portions of the upper supplemental to the pull applied thereto by the cooperative action of the wipers and the retarder, thus affording better insurance that the upper will be tightly conformed to the last and will be free from any wrinkles at the sides of the toe near the portions which have already been lasted. As the grippers are thus moved heightwise of the last their closing rods I38 move upwardly with them through the blocks MD, as a result of which the springs I 56 are further compressed and increase the pressure with which the jaws of the grippers rip the upper. These jaws. however, slip on the upper as the grippers are moved up wardly, but preferably, like the retarder, retain control of the margin of the upper until the wipers, by further advancing and closing movements, begin to wipe the marginal portion of the upper inwardly over the feather of the insole, as illustrated in Fig. 10. When the wipers have moved inwardly far enough to grip the upper effectively against the margin of the insole the drop 5153 on the cam permits the spring 88 to impart reverse turning movement to the rockshaft 52, thereby moving the retarder upwardly away from the wipers and causing the rods I 38 to open the grippers. The wipers by their continued inward movements then complete the wiping of the margin of the upper over the feather and against the lip of the insole. The lasting of the toe is thereafter completed in the same manner as disclosed in Letters Patent No. 2,160,846. It will be understood that in the return of the parts of the machine to starting positions the crossbar tea is moved downwardly by the spring 266 to return the grippers to their starting positions when permitted by the downward movement of the wiper carrier I2.
